To all whom t may concern." j

Be it known that we, KARL L. MAYERS and MAURICE lB. BENI/is, citizens ofthe United States, and residents of St. Louis, Missouri, have inventedcertain new and usefulImprovements in Vaginal Syringes, of which thefollowing is a specification. n Our invention relates to an improvement1n vaginal syringes, and haskfor its object to provide a syringe whereinair and liquid may be thoroughly combined and wherefrom the resultingcompound may be ejected in the form of a thin spray.

As shown in the drawings-Figurefl is a longitudinal transverse view insection ofa syringe embodying our invention. Fig. 2 is a perspectiveview of the central shaft employed in our invention and the sleevemounted thereon. Fig. 3 is a bottom plan view of a device embodying ourinvention. Fig. 4 is a transverse sectional view of the same taken alongthe line 4`-4 of Fig. 1. Fig. 5 is a transverse sectional view of thecylinder employed in our invention, showing the means whereby the sleeveis actuated, taken along the line 5-5 of Fig. 1. Fig. 6 is an enlargedperspective view of the base of the tube employed in our invention,showing in detail the manner in which it is slotted;

Fig. 7 is an enlarged view in longitudinal sec- A tion of one of thevalves employed in our invention.

As shown in the drawings, we employ cylinder 8 terminating in theprojecting stem 9 and containing a concentric tube 10, which terminatesin the stem 9. Aboutvthe stem 9 and its base we provide a soft rubberbulb 11. Within the concentric tube 10 is mounted the' inner concentrictube 11a provided near its outer extremity with the projecting lugs 12adapted to contact with the collar section 13 mounted within the stem 9near its mouth 14. Upon the inner tube 11 a the sleeve 15 is mountedprovided with the valve 16 at its lower extremity, which is adapted tobe seated in the valve-seat 17 formed at the inner end of the collar 13.The sleeve is provided at its inner end with the outwardly projectingpin 18. The pin 18 extends through the slot 19 extending through thetube 10 and its base. At its outer extremity the pin 18 is engaged withthe fork 20 mounted on the sliding rod 21. The sliding rod 21 is mountedwithin the cylinder 8 as shown in Fig. 5 5 its inner end being seated inthe socket 22, its outer end extending through vided with the opening 25which is screwthreaded to receive the stop er 26. Liquid is fed to theinterior of the cy inder 8 through the opening 25. By means of thepushbutton 24 the rotation of the sleeve 15 is accomplished, and suchrotation, by means of the curvature of the slot 19, serves to raise orlower the sleeve 15in position upon thetube 11 a, -to seat or unseat thevalve 16.

The cylinder 8 is provided at its open end` with the shell 27, which isscrew-threaded into the mouth of the cylinder 8 as indicated by thenumeral 28, and is provided with the concentric opening 29, which isscrew-threaded, to receive the base of the inner tube 11 a.

On the base of theshell 27 valves 31 are i provided, lwhich valves 31are formed in the) following manner: A circular series ofperfoi-ations32 extending throu h the base 30 are covered by a single flap-va ve 33which is `heldin place u on theinner side of the base j 30 by means oi acap 34 and screw 35. base 30 is also provided with the central valve The36, which is of the same construction, being provided with a circularseries of perforations 37 covered by a single flap-valve 38 held inplace by means of the screw 39.

The shell 27 is cylindrical and contains the iston 40 actuated by therod 41 and handever 42, to which it is connected by the pivot 43. Thearm 44 of the hand-lever 42 is ivotallyconnected to the bar 45 whic ishinged as indicated by the numeral 46 to a lug 47 mounted upon the base48; which base 48 is screw-threaded over the mouth of the shell 27, andisprovided with the air inlets 49.

The base of the tube 10 is provided with slotted openings 50, affordingaccess from the chamber 51 formed within the cylinder to the orilice 52which is formed by the outer surface of the tube 11a and the innersurface of the tube 10.

The mode of operation of the form of our invention which is illustratedin the drawings is as follows: The valve 16 being seated in place withinthe valve-seat 17 by means of the push-button 24 and its connections, a

small quantity of liquid is placed within the stopper 26. The piston isthen operated by means of the hand-lever 42 on the out- Ward stroke ofthe piston 40 air being admitted to the chamber 53 through the valve 36,and on the inner stroke of the piston, the valve 36 closing, air isforced through the valves 81 to the chamber 51.

It should be understood that during the operation of the air-pump, thesyringe is inverted with the stem uppermost, so that the compressed airis forced directly into the liquid contained in the cylinder S, and isso diffused during the operation of pumping that the liquid is chargedwith air to any d esired degree. This' operation being conipleted, thevalve 16 1s unseated from tno valve-seat 17 by means of the push-button24 and its connections, and the contents of the cylinder 8 are expelledfrom the mouth 14 of the stem 9 in an annular spray; the stem 9 havingan annular depression upon its inner surface near the mouth 14,indicated by the numeral 53, and the mouth of the inner tube 11a beingprovided with an annular enlargement 54; y reason of this formation ofthe mouth of the tube 1l and the mouth of the stem 9, the syringe isprovided with a 'line annular orifice 55 through which the contents ofthe syringe is ejected in a fine mist or spray,

the air and liquid being in perfect admixture and the resulting vaporconsisting` of finely comminuted moisture-laden partie es.

To those skilled in the science of gynecology, the manifold uses of thedevice of our invention will be obvious, and for that reason they neednot be expressed at length in this specification. lt will be sufficientto state that the device of the invention is intended Y for theimmediate application of cleansing or Y from its use, as in the case ofthe impact of imperfectly vaporized liquid. Furthermore, the pressureunder which the vapor is expelled distends the folds of the walls of thevagina and thus admits of the thorough cleansing and treatment of suchwalls.

The fluid is withdrawn from the vagina through the tube 11 1 and valve53, by means of the piston 40; the bulb 11L preventing the escape of thefluid from the mouth of the vagina.

In the claims we will refer to the cylinder S as a liquid-container, andthe shell 27 and its attachments as an air-pump.

Having fully described our invention, what we claim as new and desire tohave secured to us by the grant of Letters Patent, is:

1. ln a vaginal syringe, a liquid-container having a nozzle comprisinginner and outer connecting tubes, an air-pump, an inlet valve connectingthe inner tube to the interior ol' the air-pump, outlet valvesconnecting the air-pump with the interior of the liquid container, meansfor closing the nozzle ol' the liquid-container while forcing air fromthe ai rpump into the fluid contents of said container, and means foropening said nozzle alter the fluid has been charged with air,substantially specified.

2. In a vaginal syringe, a liquid-container having a nozzle comprisinginner and outer connecting tubes, an air-pump, an inlet valve connectingthe inner tube to the interior oll the air-pump, outlet valvesconnecting the air-pump with the interior of the liquid container, meansfor closing the nozzle of the liquid-container while forcing air fromthe air-pump into the iluid contents of said container, means foropening said nozzle al'ter the fluid has been charged with air, and abulb mounted about said nozzle, substantially as specified.

In testimony whereof, we have signed our names to this specification, inpresence ol' two subscribing witnesses.
